Lease agreement brandenburg, germany

A well-drafted, legally secure lease agreement is the foundation for a trouble-free landlord-tenant relationship. In Brandenburg, residential lease agreements are subject to the strict provisions of the German Civil Code (BGB), which has been in effect since 1 January 1900. We show you what you need to pay attention to when drafting one.

Written Form vs. Verbal Agreement

In principle, residential lease agreements in Germany can also be concluded verbally.

However, there is a fundamental exception (§ 550 BGB): Lease agreements that are concluded for a period of more than one year must be in writing. If this written form is not observed, the contract is legally deemed to be concluded for an indefinite period. In such cases, termination is permissible at the earliest at the end of one year after handover, subject to statutory notice periods.

For landlords, a written contract is essential anyway, since many advantageous agreements (e.g., the transfer of cosmetic repairs to the tenant) would be invalid without written proof.

Mandatory Components of a Lease Agreement

According to § 535 BGB, a valid lease agreement requires only three essential elements (Essentialia negotii). Other components are considered ancillary agreements (Accidentalia negotii):

1. Contracting Parties: Precise designation of the landlord (Vermieter) and the tenant (Mieter). Only these are the legal contracting parties.
2. The Rental Property: Precise description of the premises (street, house number, floor, apartment number). Note that a tenant may only reduce the rent if the actual living space is more than 10% smaller than stated in the contract (BGH VIII ZR 144/09). For the calculation of operating costs and rent increases, the actual floor area is decisive, regardless of contract statements (BGH VIII ZR 266/14).
3. Start of Lease: The specific date of the handover.
4. Rent Amount: The agreed-upon compensation for use. While service charges (§ 556 BGB) are common, they are ancillary and not required for the contract's basic validity.
5. Security Deposit: An ancillary agreement capped at three times the monthly net cold rent (§ 551 BGB). The tenant has the statutory right to pay this in three equal monthly installments, with the first installment due at the start of the tenancy.

Fixed-Term Contracts (Zeitmietvertrag)

Landlords cannot arbitrarily limit the term of a residential lease agreement. A fixed-term lease agreement (Zeitmietvertrag) is only legally effective according to § 575 BGB if the landlord notifies the tenant in writing of one of the following permissible reasons for the limitation at the time the contract is concluded:

• Personal Use (Eigenbedarf): Intent to use the premises for themselves or family members after the fixed term expires.
• Renovation/Demolition: Intent to significantly alter or demolish the building.
• Service Housing: Intent to rent to a person bound by a service agreement (e.g., an employee).

If the justification is missing or legally insufficient, the lease agreement automatically qualifies as being concluded for an indefinite period.

Brandenburg Specifics: Rent Control

In 36 municipalities in Brandenburg identified as having "tight housing markets" (including Potsdam, Falkensee, and Bernau), specific regulations apply as of 2026:

• Mietpreisbremse (Rent Brake): Under the Mietpreisbegrenzungsverordnung, the rent for new contracts may not exceed the local comparative rent by more than 10%, unless specific exceptions (such as new builds or the first rental after modernization) apply.
• Kappungsgrenze (Cap on Rent Increases): A lower cap applies to rent increases within existing contracts to prevent rapid escalation to the local comparative level.

Common Invalid Contract Clauses

Many pre-printed lease agreements contain provisions that are inadmissible according to the jurisprudence of the Federal Court of Justice (BGH). Such clauses unreasonably disadvantage the tenant and are therefore void.

Examples of invalid clauses:

• Rigid deadlines for cosmetic repairs: (e.g., "The kitchen must be painted every 3 years" regardless of actual wear and tear).
• Color specifications during the lease term: The landlord may not dictate to the tenant how to paint walls during the lease term. Only upon moving out can neutral tones (e.g., white or light) be demanded.
• Commercial final cleaning: The clause requiring the tenant to always have the apartment professionally cleaned upon moving out is usually inadmissible (broom-clean is generally sufficient).
• Absolute pet ban: A general ban on dogs and cats is void. Such clauses must be replaced by an individual assessment and "reservation of the landlord's permission". Small animals can generally not be banned.

House Rules (Hausordnung)

House rules regulate cohabitation in the building (e.g., quiet hours, stairwell cleaning). They are binding if they are expressly included as part of the contract in the lease agreement. If they are merely handed to the tenant or pinned to the bulletin board, they do not acquire full legal binding force, especially if they stipulate duties that go beyond mere consideration.
